Remote control having push-pull blade with captive rolling elements

摘要

Remote controls of the type in which a push-pull blade extends through a tubular sheath and is supported on its opposite sides by rolling elements held spaced from one another by cage strips are improved by providing openings in the push-pull blade to capture the rolling elements and thus obviate the cage strips. A feature of the improvement is that the openings in the blade are dimensioned to permit the rolling elements on opposite sides of the blade to be in rolling contact with each other.
